MIGUEL DE LA VEGA AND LUIZ DOLIVERIA, OF NEW YORK, N. Y.

MANUFACTURE OF SOAP.

SPECIFICATION forming part of Letters Patent No. 249,506, datedIQTovember 15, 1881. Application filed Decembdr 3, 1880. (Specimens) Toall whom it may concern:

Be it known that we, MIGUEL DE LA VEGA and LUIZ DOLIVERIA, citizens ofthe United States and residents of the city, county, and State of NewYork, have invented a new and useful Improvement in the Manufacture ofSoap,'of. which the following is a full, clear, and exact description. v

The object of our invention is to make a new and improved soap, of whichcaster-oil is the main ingredient.

The proportions in which and the mode which we prefer in making our soapare as follows: We take one thousand pounds of castoroil, and to thesame we add from ten to one hundred pounds of caustic soda and from tento one hundretTpduh'ds of potash, these two latter inghedieii'ts"offiafistlgsgda and potash being added in such proportionswithin the'limits named according as it is desired to make a softer or aharder soap. To the mixture so obtained we add fifty per cent. of water.This mixture of the water, caustic soda, and potash with the caster-oilmay be effected by either the hot or cold process used in makingordinary soap. After being thus treated, the mixture is solidified, andthe soap is then ready for use.

By using the amount of ingredients above stated about eighteen hundredpounds will be produced.

In making a greater or less amount of soap at any one time the aboveamounts of ingredients must be varied, about the same relativeproportions, however, being preserved.

We do not intend to confine ourselves to the exactproportions abovespecified, but the same may be somewhat varied without affecting theprinciple of our invention.

The soap so made is whiter, cleaner, purer, cheaper, and harder, and isconsequently more durable and cleans better, than the ordinary soaps. r

We are aware that in one or two chemical treatises mention is made ofmaking soap from castor-oil; but the proportions of ingredients thereinspecified are so inaccurate when applied to making soap from castor-oilon a large and commercial scale, as is the design of our improvement,that the process described in such books is practically worthless. Thesoap so made by such laboratory process is also inferior and not asdurable as ours, and not a practical commercial article.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

As a new article of manufacture, a new and improved soap of castor-oilconsisting of cats tor-oil, potash, caustic soda, and water,substantially as described.

In testimony whereof we have hereunto set our hands this 2d day ofDecember, 1880.
